This invention relates to a'vaporizer and supercharger for internal combustion engines, the general object of the invention being to provide means for thoroughly vaporizing the-explosive mixture before introducing the same intothe cylinders of the engine, thereby greatly increasing the etficiency of the engine, reducing the consumption of fuel and preventing overheating and carbonizetion of the engine. i

The present invention is an improvement over that forming the subject matter of applications filed by me on October 11, 1929, Serial No. 399,029, and on May 21, 1930, Serial No. 454,390.

The specificobject'of the present invention is to improve and simplify the construction and operation of the device and to provide an auxiliary air supply which is controlled by an automatic valve. w q This invention also consists in certain other :Eeatures of construction and in=the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the acoompanying drawings and specifically pointed out intheappended claims. 1 I. -."In-describing the invention in detail, reference will be hadto the accompanying-drawings wherein like characters denote like or corresponding parts throughout the several yiews,.and in;which:- v

Figure 3is a section on line 3-'3 of Figurel. A

Figure 4 is a section on line 4-4 of Figure 3.

In these drawings, the numeral lindicates a cylinder, the bore of which is shown at 2, and .said cylinder is formed with an annular chamber 3 which is separated from the bore bythe walls A. The cylinder is formed with two sections which are boltedor otherwise connected together, as shown at 5, and the abutting ends of the walls 4. of the two sections-overlap as shown at 6, to provide a gas-tight joint when the two sections are placed together. I

.- A chamber 7 isformed at one end of the bore and anoutlet port 8 is in communication with the other end, this port being connected with the inlet manifold 9 of the engine. A port l0places the chamber 7 in communication with a carbureter 11 or other source of fuel supply and a passage 12 connects the chamber 7 with the atmosphere. Thls passage is normally closed by a 'valve 13, the spring 140i which is adjustable by means of a nut 15 011 the stem of the valve. A conduit 16 connects one end of the chamber 3 with the-exhaustmanifold of the engine and an outlet port 17; connects the other end of tlic chamber with a pipe 18 which is connected wlth the exhaust pipe of the engine.

A valve 19 controls the flow of exhaust ,gasesthrough the conduit 16 and a gear 20 is fastened to the stem of the valve andis located in'a housing 21 in which is also placed .a gear 22 which meshes with the gear 20 and wh ch is engaged by a segmental rack 23 carried by a'thermostatic member 24 so that the movement of the member will be communicated to the valve. The thermostatic member is carried'by a tube 25 which extends into an enlarged part of the chamber 3-80 that the thermostatic member is acted on by the exhaust gases passing through the chamber 3.

The tube 25 is held in place by a conical nut 26 threaded in a part of the casing and having its upper part split and of conical shape so that when the nut 27 is tightened on the split part, said part will be caused to grip the tube. A finger 28 is connected with the gear 22and cooperates with a dial member 29 in the housing to indicate the temperature of the exhaust gas chamber of the device. The finger and dial member are visible through a window 30 in the housing.

A shaft 31 passes through the bore of the cylinder and has its ends journaled in the brackets 32 connected with the ends of the cylinder and this shaft is rotated from a movable part of the engine through means of a belt 33 or any other suitable means. Fan blades 34 are connected with the shaft and a spiral'or helical 35 of foraminous material is connect-ed with the shaft. Any suitable number of baflies 36 are also connected with the shaft and are formed of foraminous material and are located between the convolutions of the spiral. I prefer to place the fan adja: cent the chamber 7 and to extend the spiral from said fan to the outlet end of the bore, as shown, though I do not wish to be limited to this specific arrangement of these parts.

From the foregoing it will be seen that the explosive mixture first enters the chamber 7 and then passes through the bore to the'port 8 through which it passes into the inlet manifold and during its passage through the bore, the mixture is acted on by the fan, the spiral and the baffles which are all rotating in the bore. The mixture is also heated by the prodnets of combustion passing through the chamber 3. Thus the mixture will enter the cylinders of the engine in a highly combustible state and air is automatically added to the mixture when the engine picks up speed through the valve controlled air port 12. The thermostatic means automatically control the temperature of the mixture, for when the thermostatic means come into action, the valve 19 is closed, which prevents the exhaust gases from entering the chamber 3 of the device.

While the drawings show the thermostatic device located in the chamber 3, I do not wish to be limited to this arrangement, as it might be desirable to extend the device into the bore 2, so that the thermostatic device will be acted on by the explosive mixture itself. p Thus I have provided means for thorough- 1y vaporizing and co-mingling the explosive mixture before the same enters the cylinders of the engine, the mixture being heated by theexhaust gases'from the engine and the temperature to which the mixture is heated being automatically controlled by the thermo- 5 static device. V

' This invention will produce'a highly com .bustible mixture which will enable the engine to start quickly. The milesper gallon is greatly increased, and overheating and carbomzation of the engine is prevented.
